system: Enable/Disable low power idle in run time
We have enable_sleep()/disable_sleep() to enable/disable
EC deep sleep mode in runtime.
Here we introduce similar interfaces to enable/disable
EC idle (sleep) mode.
BUG=b:78792296
BRANCH=scarlet
TEST=Confirm idle mode is enabled/disabled when
enable_idle() and disable_idle() are called.
